    In a single throw of a die, what is the probability of getting a number smaller than 3?

    A)               \[\frac{1}{2}\]                       

    B)  \[\frac{1}{3}\]

    C)  \[\frac{2}{3}\]                      

    D)       \[\frac{1}{4}\]

    Correct Answer: C

    Solution :

     When a die is thrown, we have S= \[\left\{ 1,2,3,4,5,6 \right\}.\] Let E = event of getting a number smaller than \[3=\text{ }\left\{ 1,\,\,\,2 \right\}.\] ?P= n / n(S)\[=\frac{2}{6}=\frac{1}{3}\]
